Is our patent pending technology which the user attaches to the keys and to the locks, when the user approaches the lock the corresponding key will begin to blink letting the user know which key to open the lock.

The devices which are attached to the locks and keys do not carry a battery therefore if the user has 5 keys and 5 locks or more, the unit is only powered by one battery source.
In addition the user does not have to change over his locks or keys. The device will also vibrate to help the visually impaired.
